Abstract: This invention relates to a biodegradable anchor for a permanent implant of a bone joint, e.g. hip, shoulder, knee or finger. The biodegradable anchor is an elongated member which has an exterior surface which tightly engages a cavity in the bone and is substantially immovable within the cavity upon implant. A non-resorbable means of securing the anchor to the permanent implant is also included.

Abstract: Disclosed is a prosthetic hip joint defined by a femoral component and a cooperating acetabular component. The femoral component includes an intertrochanteric body which is press-fit into a correspondingly shaped intertrochanteric cavity at the top end of the patient's femur. Load transferring surfaces between the femoral implant and the femur are located within the intertrochanteric cavity and at the upper end of the femur. The load transferring surface are shaped to generate compressive stresses only. The femoral implant includes an attachable guide stem which can be resorbable and extends into the medullary cavity but which is not secured thereto to eliminate undesirable transference of stresses from the implant to the bone. The acetabular component is defined by an acetabular cup that is pressfit into a pre-reamed acetabular cavity in the patient's pelvis. An anchor bolt, which can be resorbable, is threaded into the pelvis, extends through a corresponding hole in the cup and is secured to the cup.

Abstract: A self-contained traction device for pelvic or cervical spine traction which can be placed on an ordinary bed is disclosed. A platform with an upwardly inclined surface is used for elevating a portion of a patient's body. A strap is attached to the portion of the patient's body to which traction is to be applied, and the other end of the strap is attached to a cable which passes over a pulley attached to the far end of the platform. The far end of the cable on the other side of the pulley is attached to a weight which provides the traction force. Because the weight is directly attached through the pulley to the platform against which the patient rests, the horizontal forces exerted by the patient's body upon being pulled by the strap are cancelled by the horizontal forces applied by the weight through the pulley to the platform so that movement of the traction device across the bed is prevented without the need for restraining it to a bed frame or the like.
